Sort 2 Chip

The chip layout follows the general architecture of the sensor. WTA rows with arrays of photodetectors can be seen on the left. The peak detectors and digital dual-ported memory are on the right. 

Here we show the drawing of the layout together with an actual micrograph of 6 pixels. Top area in each pixel is the photodetector, while the bottom is processing circuitry. The pixel fill factor is about 50%.
